STATEMENT-1: It is easier to pull a heavy object than to push it on a level ground and
STATEMENT-2: The magnitude fo frictional force depends on the nature of the two surfaces in contact.

STATEMENT-1: It is easier to pull a heavy object than to push it on a level ground and STATEMENT-2: The magnitude of frictional force depends on the nature of the two surfaces in contact.

Give a example to show that friction depends on the nature of two surface in contact.

STATEMENT -1 : In a tug of war game, the two teams always pull the masless rope with same magnitude of force . and STATEMENT -2 : The force exerted by any team on the rope is equal to tension developed in the rope which will be same at both the ends .

STATEMENT-1: During a turn, the value of centripetal force should be less than the limiting frictional force. STATEMENT-2: The centripetal force is provided by the frictional force between the tyre and the road.

STATEMENT-1: A block is pulled along a horizontal frictionless surface by a thick rope. The tension in the rope will not always be the same at all points on it. because STATEMENT-2: the tension in the rope depends on the acceleration of the block rope system and the mass of the rope.

STATEMENT -1 : In absence of air friction, it is claimed that all object fall with the same acceleration although, a heavier object is pulled towards the earth with more force than a lighter object. because STATEMENT-2 : Net external force is always equal to rate of change of linear momentum.

STATEMENT - 1 : If an object is at rest then there should not be any friction on it . STATEMENT - 2: If an object is moving then the friction acting on it has to be kinetic . STATEMENT -3 : If an object is at rest then kinetic friction cannot act on it.

STATEMENT - 1 : The value of modulus of elasticity depends on the magnitude of the stress and strain and STATEMENT - 2 : A given material have different moduli of elasticity depending on the type of stress applied.
